According to a report, clients claimed that they intended to migrate up to 80% of their apps to the cloud over a five-year period. Even while this number is already considerable, it has extra significance given that huge corporations may use hundreds of software for various aspects of their business.  The way organizations operate in the modern world has changed significantly as a result of cloud computing. Cloud services have assisted firms in strengthening every area of their operations, including business expansion, service offerings, security infrastructure, and product management.   

The adoption of cloud computing is expanding across all industries internationally. According to a recent Gartner report, $482 billion will be spent on public cloud services by 2023. In addition, Gartner forecasts that by 2026, 45% of all organizations’ IT investment will be spent on the public cloud, up from just 17% in 2022.  

We are aware that transferring data centers, workloads, and applications to the cloud offers benefits such as cost reductions, operational efficiencies, and quicker speed to market. Organizations find it difficult to properly adopt the cloud, despite the widespread acceptance and migration of clouds. In order to effectively embrace the cloud, organizations must use non-traditional Quality Engineering (QE) approaches.   

The following are the five top guidelines for a smooth transition to and usage of the cloud: 

1. The strategy of automating first and automating everything 

To increase agility and accelerate deployment, businesses go to the cloud or create cloud-native applications. Every cloud-based application is executed as code, i.e., automatically, with no need for human intervention. Such end-to-end automation is lacking when it comes to cloud assurance, which undermines the overall goal of the cloud. 

Businesses that want to fully benefit from the cloud must adopt a culture of “automate first, automate everything” for their cloud assurance process. This modern approach to automation not only focuses on in-sprint automation but also aims to automate the full automation pipeline, from test data through infrastructure to quality gates. Such zero-touch automation techniques may help to increase cloud adoption efficiently.  

2. Overcoming cloud integration complexities 

Organizations that want to move their current apps to the cloud encounter a variety of difficulties during the cloud integration phase. Access, performance, and security issues make up the majority of these obstacles. Additionally, these difficulties are compounded with hybrid cloud infrastructure, when applications are hosted in both the cloud and on-premises data centers. 

Traditional quality control techniques are insufficient to handle the hybrid cloud systems’ complexity. They frequently cause the transaction process to be a sluggish bottleneck. An automated concurrent testing framework saves the day in these circumstances. These frameworks conduct an application benchmark on the current infrastructure and contrast it with the environment that was moved. The benchmarking often includes single-user performance, URL validation using crawlers, and access validation in addition to functionality. Making decisions may be speedy and scalable with such customized test strategy migration. 

3. Verifying the Resilience and Perserverance 

Resilience is a crucial feature of cloud infrastructure and cloud native design. Although cloud services are hosted on reliable infrastructure and are generally resilient, issues still arise. Your company can concurrently concentrate on infrastructure availability/site dependability and application resilience to create a good resilient application. 

Organizations are helped to assure the resilience of the infrastructure by several methods including SLOs (Service Level Objectives), SLIs (Service Level Indicators), and SLAs (Service Level Agreements). Enterprises must use chaotic engineering methodologies in addition to these infrastructure monitoring procedures. Testing is based on the idea of Testing in Production (TiP) in chaos engineering. Here, organizations employ testing techniques like monkey testing to examine the resiliency of specific cloud-native application components while they are in operation.  

4. Expanding and maximizing the value of the cloud 

The cloud offers the flexibility to expand workloads up and down as required due to horizontal infrastructure scaling. Auto-scalability, however, also carries the risk of using far more space than is necessary, which would eventually stretch the budget. Your company must implement governance and testing of infrastructure code in order to prevent such a budget surge. 

• Monitoring: A container monitoring solution assists enterprises in validating the scalability metrics and assisting them in seamlessly optimizing the microservices environments, regardless of whether their architecture is cloud-native or migrated. 
• Iac Testing: Infrastructure as a code (Iac testing) depends on automation’s strength. To ensure the best scalability and optimization, it aids enterprises in evaluating and validating various virtual elements in the cloud infrastructure. 

Both container monitoring and Iac testing are essential components of the Quality Engineering systems that allow your company to maximize resource utilization and provide the best performance without adding additional costs to your testing budget. 

5. Excessive shift-left testing 

Monolithic software architecture has given way to scalable and flexible software architecture in the technological world. Additionally, the introduction of microservices and cloud infrastructure has made the software even more flexible. Each microservice can now be separately deployed in production to enhance time to market. 

It is not enough to shift-left testing processes in order to benefit from these capabilities without sacrificing quality. Instead, it needs to be moved even more to the left, and excessive shift-left testing must be used. 

Excessive shift-left can also be accomplished by businesses using contract testing in a microservice infrastructure. Consumer-driven contract testing shortens the time it takes to respond to integration problems by independently verifying integration between two microservices.
